Volcano plot showing the gene expression fold change between 500ppm and 1000ppm methane conditions vs a baseline of low methane. The left and middle panel are the same data but provide different interactions (brush vs. pan + zoom). The right panel is a bar chart showing the count of genes annotated in each pathway (count is doubled since genes points exist once in the 500ppm and once in the 1000ppm dataset). The height of the bars dynamically respond to the brush selection made in the left panel.
